The HMC468LP3 & HMC468LP3E are broadband
3-bit GaAs IC digital attenuators in low cost leadless
surface mount packages. Covering DC to 6.0 GHz,
the insertion loss is less than 1 dB typical up to 4
GHz. The attenuator bit values are 1 (LSB), 2 and 4
dB for a total attenuation of 7 dB. Attenuation accu-
racy is excellent at ±0.4 dB typical step error with an
IIP3 of +50 dBm. Three control voltage inputs, toggled
between 0 and +5V, are used to select each attenua-
tion state. A single Vdd bias of +5V is required.
